You can open more than document. Drag a document window by one edge or corner to resize if necessary, then drag the whole window by its title bar to one side of the screen. You should now be able to see the other document. Move that window beside the first.
You can switch between them by clicking on the one you want to be active.

Just open the two, they will be in separate windows and you can adjust them to be side by side or command shift tab to switch between them or use the Window menu to select them in turn.
Many ways you can do this.
